2012 BMW Alpina B7 Spare Tire
The BMW Alpina B7, a high-performance luxury vehicle, does not typically come with a traditional spare tire, instead it is equipped with run-flat tires which are designed to resist the effects of deflation when punctured, allowing the driver to continue to drive for limited distances at a reduced speed. This is because the Alpina B7 utilizes a staggered wheel setup, with wider tires in back, making it impractical to include a spare that would be the right size for both front and rear wheels. However, if a spare tire is needed, a full-size matching tire of the same specifications can be used. The usual tire size for a BMW Alpina B7 is 245/35R21 for the front and 285/30R21 for the rear, but always refer to the vehicle ' s manual or placard on the driver ' s door jamb for the correct replacement tire size.
2012 BMW Alpina B7 comes with 1 OEM tire size option. Select the original equipment the tire size installed on your vehicle to see all spare tires that have roughly the same tire diameter and can be used as a temporary replacement in the event of a flat tire. Remember that load carrying capacity of the spare tire must be the same or higher than the load carrying capacity of the original equipment tires in order to safely support the weight of your vehicle. Refer to vehicle owner's manual or contact BMW dealership to confirm the correct 2012 BMW Alpina B7 spare tire size.
